' 5 thefixture, being characterized by a simple and inexpensive means gfori suspending the two so that they are free toassumea'vertical position and without-the'necessity of any adjustments of the. parts thereof; suspension means capable of being readily assembled and disassembled; andja bowlhaving aremovable bottom through which access may be had to the lamp for substituting .a' new one when necessary, and without the require-- ment of removing the entire bowl, as isnecessary in lightingfixtures as heretofore proposed... n It is also a lpurpos'e of my invention to provide a bowl having transparentportions 2C and translucent portions, andm irrforedsurfaces for reflecting the rays emanating-from the lamp so that they are projected through the transparent portionsto eifect a very de sirable form of indirect lighting; '7 p -1 will describe onlyone 'form of lighting fixture embodying my invention and willthen pointout the novel features thereof in claims. ,In the accompanying drawings f V Eig. l is a view showing in side elevation F and partly in verticaljsection, one form of lightingifixture embodying my invention.

Figs. 2 and 3 are transverse sectional views taken on the lines 2 -2 and 3+3, respectively,

of Fig; 1, andlooking in the direction of the $5 arrows. V V H V l In carrying out my invention, I employ a conventional form of canopy asa finish plate for an electrical conduit 16 which projects downwardly from a ceiling and through which 'extend the flexible conductors 17 for an electric lamp 18. The conductors 17 project a distance beyond thelower endi of the conduit 16 so that the-lamp 18 is-free to assume vertical position: a The lower end of.

the conduit16 is screw threadedxexteriorly as indicated at 19 to receive a ball 20 provided witha central openingQl alignedwith the bore of the conduit16 in orderthat the conductors 17 ,may be extended through the 3 ball, as illustrated in Fig. 1; ,A socket mem- 'member and the bowl. 7

her 22 loosely memes the mun ane,

formed integral with this socket member are a plurality" o firadia-l arms 23 circumferential? ly spaced and provided" with a slot 2 1.

When'once associated with the conduit 16 the'ball and socketmeniber' remains afixed part of the conduitland constitutes thels'us pending'inember of'a means for suspending a! bowl for housing the lamp 18 tofsecure such projection of light rays emanatingfrom the lamp asto produce indirect lighting.

The .rem'ainder'of thel suspension means comprises 1 a suspended member including three hooks 25 and a flat ring 26 formed integral w th the hooksand fromwhich the latter :rise. These hooks are circumferentially V spaced toccorrespondftothe spacing of the arms 23, andthe bill of the hooks are adapted. to seat within thet'slotsQtso that the member as .a unit is suspended from the'arms. A plurality of spring clips 27 are secured to and circumferentially spaced on the upper side of the ring 26, and these clipsa're constructed 7 toreceive' and engagean annular 'bead 28 formed'on a bowl designated generally-at B,

the clips and beads coacting to provide a detachable connection" between the suspended The detailed construction of the bowll will be described"hereinafter, but suflice it i to sayfor thegpresent, that, the bowl provided wlth a restricted opening at itsupper end bounded by a colla-r 29, at the base 0-1 which, the bead 28 is formed. The bowl at its bottoln is formed with aielatively large opening bounded by a collar 30, and through this opening access is had to the lamp 18 for applyingor removing the latter and without the necessity of detaching the bowl from the suspension means. Thebottom opening is normally closed by a closure 31 preferably formed of metal or any other suitable opaque or translucent material and this closure is detachably secured to the bowl by means of spring clips 32 and 33; The clip 32is secured at the innerside of the closure so as to have engagement {with the inner 'face of the collarBO 'the clip 38' being secured to panels. 'I

as. to. provide an; exterior ornament. for. the.

closure.

In practice, the bowl B is applied to the suspension means by first associatingthe suspended member withthe upper end of the bowl, the element being inserted' into the collar 29 through the bottom, of the bowl and. to a position in which. the. clips, 2 7, engage the bead 28. It will,benotedthat once the ring. 26 1s applied, it forms a, seat for t b a 28, a h adjacent imam. 0 the hea Q ha he. usnal la l n ml e i nno pass upwardly through the: bowl. VVjth the suspended member applied as, described the hooks 2 5.are disposedju'pright within the col.- lar 29 sothat bypassing the bowl upwardly aroundthe condnctorsl'l'. to a point in, which the bills of the hooks, 25. are disposed, above the arms 23, the bowl; may nowfbe, lowered to cause the bills. to pass into the slots2a thereby operatively connecting. the sns pended member to the suspension nie nber. Thus, the bowlis now suspended onthe conduit, it being understood that in order. to position the bills of, the hooks with respect to the slots, it is necessary to. slightly rotate the bowl, With the bowl thus applied, it is suspended to swing about the ball 20 by the socket, 22, and in consequence of, which, the bowl is free to assume ,at'rue verticalposition even though the conduit 16 may notice true vertically. 1 i i In applying the bowl. as above described, the closure 31 is of course einovedbut following suspension of the bowlf-ro n'theconduit, the closureis reapplied,

The bowl, B is constructed of glass or similar material, andin addition totlie collars 29 and 30, it is formedivith body portions 36 and 37 of frusto-ronical form, the lower body portionbeing largcrthan the upper, as will be clear fron'i a consideration of 1. Both of these body portions are shaped circumferentially to provide a plurality of; facets and these facets. are frosted. in order to render them translucent. The horizontal parts 36?, and" 37", respectively, are clear or transparent glass, while the interior surfaces; of thefacets of the lower. portion 37 are mirrored, as indicated at 37?, in order to provide reflecting he ,angularity of these panels with respect tothe lamp 155 the clear glass portions. 3?? is. such that, the rays from the. lamp will be. refracted and pro jected vertically throughthe clear glass portions. As these portions are horizontally disposed, the light rays will be projected upwardly against the ceiling, and thus produce what is known in the art as indirect lighting. With respect to the bowl portion 37, those rays from the lamp 18 projecting upwardly will; pass throughthe. clear glass and thus outwardly against the ceiling. The frosted parts will be illuminated by the lamp priodnce a dull. llum na o efi i y 0f thebowl, which is desirable in fixtures of this kind.

Although I have herein shown and described only one form of lighting fixture embodying my-invention, it is to be understood that various changesand modifications may be made herein without departing from the spirit of the invention and. the spirit and scope of the appended claims.
